GAGE-LAMP.

Specification of Letters Patent.

Patented Dec. 6, 1921.,

Application filed January 24, 1920. Serial No. 353,775.

To all whom it may concern:

Be it known that I, NATHAN A. LEVITAN, a citizen of the United States, residin at Brooklyn in the county of Kings and tate York, have invented new and useful Improvements in Gage-Lamps, of which the following is a specification.

This invention relates to lamp receptacles for use primarily in connection with locomotives or similar machinery and has for one of its objects the provision of a device of this character which is particularlydesigned as a container for a standard or stock form of incandescent lamp and for effectively concealing the direct glare of light from the eyes of the engineer or attendant and for, directing a light ray toward and against the object or objects intended to be visualized such as the steam, air brake or lubricating gage of a locomotive equipment.

Another object of the invention is to pro vide a structure of the described character in which will be incorporated means whereby the incandescent lamp, normally carried by the structure can be readily separated therefrom so as to permit it to be used as a trouble finding lamp in cases of emergency where the engineer or attendant desires to examine a particular part of the equipment of the locomotive when making repairs thereto.

Another object of the invention is to pro-' vide a device of the class specified in which the incandescent lamp can be inserted in or removed from its container without possibility of breaking the same.

Another object of the invention is to provide a lamp container adapted to inter changeably receive sections or light projecting parts of a design particularly intended for a given purpose.

With the above and other objects in view which will appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangements of parts which will hereinafter be 'fully described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated, a sin 1e and preferred form of the inventlon, it eing, however, understood that no limitations are necessarily made to the precise structural details therein exhibited, but that changes, alterations and'modifications within the scope of the claims may be resorted to when desired.

Figure 1 is a side view of the container.

Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a side view of several forms of interchangeable plates or sections of the structure.

Fig. 4: is a sections.

Fig. 5 is a plan view of the device.

In carrying the invention into practice, use is made of a container 5, the same consisting of a relatively fixed section 6 and a mov' able section 7, the latter hinged to the former at 8. The sections are semi-cylindrical preferably and the hinged connection between said sections is located at the point between the sections as clearly illustrated in Fig, 2. At a point diametrically opposite plan view of said plates or the hinge the section 7 is provided with a clasp 9 which is adapted to engage with a keeper surface 10 on the section 6 so as to hold both sections closed, one against the other normally. The section 6 is provided with a depending attaching boss 10 threaded at 11 for connection with a suitable pipe section or the like which is adapted to con-- stitute a supporting column for the structure.

The sections are provided at their upper ends with suitable openings 12 the same arranged side by side and adapted to receivea plug 13 which extends into the receptacle, and as shown, said plug is threaded at 14 for operative connection with a socket 15. The socket may be of any suitable well known construction adapted to be arranged in an electric circuit and to receive an incandescent lamp of the kind shown at 16. The arrangement just described is such that the lamp 16 is hung or suspended from the top oii the casing and in a position whereby when the section 7 is moved to an opened position, the open side of the section 6 will be exposed to enable the operator to place his hand in said section when it is desired to manipulate the lamp 16 to effect its removal from or insertion in the socket 15. The construction is also such that suflicient clearness is provided between the walls of said section 6 and the lamp 16 so that all possibility of knocking the lamp against the walls of said section 6 is eliminated.

In order that the plug 13 and the lam 16 carried thereby can be entirely removed rom the container when it is desired to use the lamp for emergency purposes, I provide the said plug 13 with a flange 17 adapted to be secured to the upper end of the container by removable fastenings such as screws 18, the latter entering the adjacent wall of the section 6 as illustrated in igs. l and 5. By simply removing these screws and opening the sections 7 of the container, it will be observed that the lamp 16 can be withdrawn laterally from the open side of the section 6. The socket 15 will of course be provided with a suitable flexible cord 19 containing the circuit wires. Sufficient cord is provided whereby the lamp can be. 0 eratively extended to the point where the light to be utilized is desired.

In devising the structure it is among the several objects previously referred to that in addition to concealing the direct flare of light, means be incorporated in the structure whereby a part thereof can be quickly and conveniently separated to permit of the substitution therefor of a slightly differently formed part when it is desired to cause the light to be reflected in a given direction or upon an object or objects intended to be illuminated and visualized. In order to accomplish this last purpose. I provide the section 6 with an opening 19 with which plates A, B and C are adapted to be. interchangeably associated and secured to the side walls of the section 6 in some suitable well known detachable manner such as by means of fastening screws 20. The plate A is provided with a light projecting opening 21, defined by a cylindrical extension 22 formed as a part of said plate. The opening 19 is arranged in lateral alinement with the. lamp 16 so that the light ray emanating therefrom will be delivered through the opening 21 from which it may be centered and cast upon the object to be illuminated such as the steam gage of a locomotive.

The plate B, is provided with a plurality of superposed openings 23 and 24 each of which is defined by a cylindrical extension 25 formed as part of said plate; The extensions are arranged at relatively diverging angles so that a ray of light from the opening 23 will be distributed at an angle opposite to a From the above construction, it will be observed that the principal body of the contalner constitutes a stock fixture and when it is desired to put the fixture to a given use, it can be readily e uipped with any one of the several forms 0 light rojecting or distributing plates shown at B and C. This obviates the necessity of the owner of the structure having to purchase a new fixture for the particular pur se for which such fixture is intended. 11 other words, the structure is capable of being readily converted from one design to another with ease and dispatch and at a comparatively small cost.

The side edges of the sections 6 and 7 are respectively provided with cavities 30 and projections 31, the latter fitting the former so as to close the points between the parts against the projection of light therethrough.

What is claimed as new is A device of the class described, comprising a pair of sections hingedly connected together at one side and having their co-acting edges formed with interfitting elements, and one of said sections formed with a side opening a flanged plug removably secured to one of said sections, a light bulb in said plug and in line with the aforesaid opening, a boss whereby said-device may be supported, and a removable section having a tubular extension secured over the aforesaid opening for projecting the light from said device, as'and for the purpose described.

In testimony whereof I have aflixed my signature.
